Answer: 11
Step-by-step explanation:
Let the 5 numbers be x,x+1,x+2,x+3 and x+4.
Therefore,
x + x+1 + x+2 + x+3 + x+4 = 65
5x + 10 = 65
5x = 65 - 10
5x = 55
x = 55/5
x = 11
Therefore, the 5 numbers are 11, 12, 13, 14 and 15.
The first number is 11
Answer:
18x + 28 is the perimeter
Step-by-step explanation:
As perimeter is the som of all side
So P = 6x+8 + 3x+6 + 6x+5 + 2x+2 + 3 + x+4
= 6x+3x+6x+2x+x + 8+6+5+2+3+4
= 18x + 28
Answer:
I believe it's A=5 times 9 but since the triangle is special (3-4-5), it could be 12 times 5. Hope this kinda help :)
Answer:
2048
Step-by-step explanation:
Formula for volume of a sphere is given:
V = 4/3πr^3
Where r = radius
The sphere shown has a given radius of 8
All we have to do to find the volume of the sphere is simply plug in the given value of the radius (8) into the volume of a sphere formula
(Note it says use 3 for π )
V = 4/3(3)r^3
Substitute 8 for r
V = 4/3(3)(8)^3
Plug this into a calculator and you get that the volume is 2048
